trying to transcode .ts returns "regex match on video stream data failed"

[douginoz]

Attempting to run pytranscoder on a bunch of .ts files. ffmpeg has no problem when used directly but pytranscoder fails:

pytranscoder --dry-run -v recordedshow.ts
>>>> regex match on video stream data failed: ffmpeg -i recordedshow.ts

Could you paste in the output from: ffmpeg -i <yourfile.ts> Then I can look for the differences.

Thanks for the thorough bug report. pytranscoder requires a minimum amount of media information to support the rules engine. If a specific media file doesn't expose that data, or does so in an atypical way, then it cannot behave as designed. However, I've added an additional layer of media analysis as a backup if the primary fails. This may help is some situations, but if the baseline data needed for pytranscoder to function isn't available there isn't much else I can do. Look for version 2.0.13 dropping within 24 hours. I hope it helps.

The PR I just opened is related to this issue. On failing to parse the metadata for .ts files and then falling back to ffprobe with json parsing, an additional error occurs when casting the value of duration to an integer if ffprobe returns a floating point value quoted as literal.
